Interface DynamicUpdateHandler

public interface DynamicUpdateHandler

Use DynamicUpdateHandler to process any update dynamically. This is useful for library-level code and implementation of DSLs.

Use Workflow.registerListener(Object) to register an implementation of the DynamicUpdateListener. Only one such listener can be registered per workflow execution.

When registered any updates which don't have a specific handler will be delivered to it.
